2) Great white sharks are big and hungry. Here is a sample of lengths in feet of great whites:  18.7 12.3 18.6 15.7 18.3 14.6 15.8 14.9 17.6 13.2  12.1 16.4 16.7 17.8 16.2 12.6 17.8 13.8 12.2 15.7  15.2 14.7 12.4 13.2 15.8 14.3 16.6 9.4 18.2 19.7  13.2 13.6 15.3 16.1 13.5 19.1 16.2 22.8 16.8 18.7  13.6 15.3 16.1 13.5 19.1 16.2 22.8 16.8 13.6 13.2    Your report must include, but not limited to the following points.  a) Make a frequency distribution of the data set using eight classes. Include class limits, midpoints, boundaries, frequencies, relative frequencies, and cumulative frequencies.   b) Display the data using a frequency histogram and a frequency polygon on the same axes.   c) Display the data using a stem-and-leaf plot. Use one line per stem.

The heights (in centimeters) of some randomly selected Men's World Cup soccer players from both Europe and the U.S. are given below. Europe 169 170 171 175 175 175 178 180 181 182 184 185 185 187 189 United States 167 168 169 173 176 176 178 180 180 181 183 183 186 187 187 Is there a difference between the heights of European and American soccer players? What is the test statistic for this test? 0.7399 0.3352 0.3700 0.6648 0.2601

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights​ (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts​ (a) and​ (b) below.   Height (cm) of President 191 182 179 183 200 174   Height (cm)of Main Opponent 183 185 178 181 184 176 a. Use the sample data with a 0.01significance level to test the claim that for the population of heights for presidents and their main​ opponents, the differences have a mean greater than 0 cm.   In this​ example, μd is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the​ president's height minus their main​ opponent's height. What are the null and alternative hypotheses for the hypothesis​ test?     Identify the test statistic. t= Identify the​ P-value.   ​P-value =   What is the conclusion based…
